Wanted: Books / Info on Using Advanced ICs in Electronics

  • Hey there guys. I couldn't think of a better group than you guys to ask.

    I've been teaching myself a ton of stuff in electronics lately and Know intermediate AVR programming but I'm kinda running into an information wall right that I hope someone could help me break.

    I'm looking into building a circuit that utilizes 3G Cell Technology. I could easily prototype something using either the official GSM shield from Arduino or some other third party shield no problem, but I want it to go beyond just a prototype, so I need Books/Textbooks/websites anything that discuss how to know the specs of Advanced ICs such as those and how to address then within the digital logic of my circuits. Something that would help me Pop it into a custom PCB design etc etc. Any help would be appreciated. Thanks.
